Description

Technical Field

[0001] The present invention relates to the technical field of seeders, and particularly relates to a ridging seeder. Background Art

[0002] A peanut ridging seeder is a composite agricultural machine integrating functions such as soil tillage, ridging and forming, fertilizing, sowing, and film mulching. It is designed for the precision sowing of crops such as peanuts. Its core function is to construct a standardized ridge body to optimize the soil structure, drainage performance, and crop growth environment, and at the same time achieve single-seed or double-seed precise sowing, significantly improving the sowing efficiency and emergence quality.

[0003] Currently, peanut ridging seeders are usually towed by tractors. During the towing process, the ground wheels are driven to rotate, and power is distributed to each functional module through a transmission system to achieve rotary tillage and ridging, break up the soil and remove straw. Subsequently, the broken soil is gathered towards the midline by a curved forming plate to form a ridge body, and low positions on both sides of the ridge body form furrows. Then, fertilization is carried out in the above-mentioned furrows, furrows are opened on the ridge surface at the top of the above-mentioned ridge body for sowing, and finally, soil covering and compaction are carried out, thus completing the ridging and sowing operation. Among them, based on the peanut seed characteristics and sowing requirements (such as two-seed precise sowing), the sowing mechanism usually adopts a pneumatic seed metering device, which can accurately suck the target number of peanut seeds for sowing.

[0004] In the prior art, rotary tillage (or non-rotary tillage) is usually directly carried out through a ridging roller for forming, resulting in uneven distribution of soil resistance (especially in clay or straw-covered land), leading to large deviations in ridge height and ridge top width, affecting subsequent sowing accuracy. During the ridging process, it is easy to cause the soil piles on both sides to be loose. During subsequent compaction, the soil is backfilled into the furrows. In addition, after furrow opening and sowing, due to the soil spreading to both sides, direct compaction will cause the soil to flow laterally, resulting in uneven soil covering thickness, and at the same time, the soil on the ridge top is pressed into the furrows, thus causing the ridge shape to be damaged. Summary of the Invention

[0005] The purpose of the present invention is to provide a ridging seeder to solve the problems raised in the above background art.

[0006] To solve the above technical problems, the technical solution adopted by the present invention is: A ridging and seeding machine comprises a machine body; further comprising: a front furrow plow, installed at the front of the machine body, used for pre-loosening the soil and opening shallow furrows before ridging; a ridging mechanism, comprising a columnar portion and conical portions located at both ends of the columnar portion, used for squeezing the soil on both sides toward the middle to form a ridge body, and compacting the shallow furrows on both sides of the ridge body to form ridge furrows, and anti-slip teeth are fixedly connected to the outer periphery of the conical portion at equal intervals; a furrow opener, used for opening a deep V-shaped seed furrow on the ridge surface at the top of the ridge body; a sowing mechanism, used for quantitatively sowing seeds; and a fertilizing mechanism, used for applying fertilizer to the ridge a compensating mechanism for sowing additional seeds when the sowing mechanism misses sowing; a transmission mechanism for utilizing the rotation of the ridging mechanism to generate power to drive the sowing mechanism and the fertilizing mechanism to work, including a sprocket and chain for connecting the central axis of the ridging mechanism and the sowing mechanism and the fertilizing mechanism; a rear ridge plow for repairing the ridge shape destroyed after furrowing, reshaping the ridge shoulder after furrowing and sowing, gathering the overflowing soil through the curved profiling plate, and restoring the trapezoidal cross-section; a suppressing mechanism installed at the rear of the machine body for compacting the seed furrow and the surface soil of the ridge body.

[0007] By adopting the above technical scheme, by setting up a front furrow plow, shallow furrows can be plowed in advance before ridge forming, and the position of the shallow furrow is exactly the path of travel of the conical parts located at both ends of the ridging mechanism. The ridging mechanism can form ridges based on the soil pile between two adjacent shallow furrows. During the ridging process, the conical part of the soil extends into the shallow furrow and applies force to the central part, thereby avoiding the soil at the edge (the original shallow furrow position) being excessively compacted by the conical part; and a rear ridge plow is set to "repair" the ridge body after furrowing and sowing, and push the soil scattered during the sowing process back to the top of the ridge, so as to avoid the damage of the ridge structure due to the backfilling of soil into the ridge furrow after sowing and compaction by the suppression mechanism, which is beneficial to the maintenance of the ridge structure.

[0008] A further improvement of the technical solution of the present invention is that the sowing mechanism includes a seed box and a seeding shell, the mouth of the seeding shell is fixedly connected to a protective shell, one side of the inner wall of the protective shell is rotatably connected to a driving shaft, one end of the driving shaft is fixedly connected to a seeding plate, and a driving structure for controlling the rotation of the driving shaft and the seeding plate is arranged inside the protective shell; the seeding plate is in contact with the mouth of the seeding shell, a plurality of suction holes arranged in a ring are provided on the seeding plate, and a ring-shaped partition plate is fixedly connected to the side of the seeding plate close to the protective shell, and the interior of the partition plate is equidistantly divided into chambers equal in number to the suction holes, and the partitions are The inner wall of the disk is provided with connecting holes whose number is equal to that of the chambers and are connected; the inner wall of the separating disk is rotatably connected with a distribution disk, which is fan-shaped and has air grooves on the side walls, and a sealing ring is arranged between the distribution disk and the separating disk, and an air pump is fixedly installed on the machine body, and the air pump is connected with the distribution disk through a pipeline; a feed pipe connected with the seed box is arranged on one side of the seed discharging shell, and a discharge pipe is arranged at the bottom, and the bottom end of the discharge pipe extends to the inside of the furrow opener, and a partition plate is fixedly connected to the inside of the seed discharging shell, and the discharge pipe and the feed pipe are respectively located on both sides of the partition plate; the aperture of the suction hole is larger than the connecting hole.

[0009] With the above technical solution, by dividing the separating plate shared by each material suction hole into several independent chambers, and each independent chamber is commonly connected to the distribution plate. By evacuating the distribution plate and then using the communication holes facing the air grooves to transfer negative pressure, the negative pressure can be transferred to the chambers facing the air grooves. In the above process, the distribution plate acts as a pressure stabilizing tank, and the external air pump only needs to continuously maintain the pressure value of the above distribution plate. Since the distribution plate and each chamber of the separating plate are also connected through communication holes, due to the existence of an additional transfer chamber and being restricted by the aperture of the communication holes, the mutual disturbance effect between each material suction hole is reduced, thereby reducing the influence of air pressure change on the seed adsorption effect.

[0010] A further improvement of the technical solution of the present invention lies in that: the driving structure includes an external sprocket wheel fixedly connected to the outside of the driving shaft. A driving wheel is rotatably connected to the inner side of the protective shell. One side of the driving wheel is fixedly connected with a first shifting lever, and the first shifting lever is used in cooperation with the notch outside the sprocket wheel. The central axis of the driving wheel extends to the outside of the protective shell and is in transmission connection with the ridging mechanism through a transmission mechanism.

[0011] With the above technical solution, by setting a sprocket wheel mechanism, the seed feeding mode of the seed discharging plate is changed from a continuous type to an intermittent type (that is, it stops after rotating a certain arc, then rotates and stops again, cycling but the overall rotation period remains unchanged), so that there is enough time for the material suction operation during the stop interval of the rotation of the seed discharging plate, thereby increasing the probability of seed adsorption and reducing the occurrence of missed seeding; specifically, during the rotation of the ridging mechanism along with the machine body, the driving wheel is driven to rotate through the transmission mechanism, and the first shifting lever is driven to rotate around the central axis of the driving wheel, and the sprocket wheel is periodically shifted, so that for each rotation of the driving wheel, the corresponding sprocket wheel rotates a certain arc, making the driving shaft rotate intermittently during the rotation of the ridging mechanism, thereby driving the seed discharging plate to rotate intermittently.

[0012] A further improvement of the technical solution of the present invention lies in that: an internal sprocket wheel is rotatably connected to the side of the distribution plate away from the seed discharging plate. The central axis of the internal sprocket wheel is a hollow shaft. A second shifting lever is fixedly connected to the side of the driving wheel away from the first shifting lever, and the second shifting lever is used in cooperation with the notch inside the internal sprocket wheel; the driving shaft is a hollow rod, and a core rod is rotatably connected inside the driving shaft within the protective shell. One end of the core rod extends to the inside of the seed discharging housing through the driving shaft and is fixedly connected with a feeding blade; a driven gear is rotatably connected to the inner side of the protective shell. A driving gear ring is fixedly connected to the outer wall of the internal sprocket wheel, and the driving gear ring is meshed with the driven gear. The central axes of the driven gear and one end of the core rod both extend to the outside of the protective shell and are in transmission connection through a synchronous wheel and a synchronous belt.

[0013] With the above technical solution, by setting the material shifting blades, the stacked seeds can be shifted to reduce the weight of the seeds stacked in the middle, enabling the seeds located below to move during the movement of the machine body, thereby increasing the probability that the seeds in the middle are directly opposite the material suction holes. Specifically, during the rotation of the drive wheel, the second lever will also be driven to move in a circular motion around the center of the drive wheel, and periodically shift the Geneva wheel, causing the Geneva wheel to rotate intermittently. Through the transmission of the synchronous wheel and the synchronous belt, the core rod is driven to rotate, and further, the material shifting blades are driven to rotate, thus shifting the seeds in the middle to one side, reducing the accumulation of seeds in the middle, and enabling the seeds near the lower part in the middle to move along with the movement of the machine body. It should be particularly noted that the Geneva wheel and the external Geneva wheel share one drive of the drive wheel for operation, and their operating states are opposite, that is, when the Geneva wheel rotates, the external Geneva wheel is stationary, and when the external Geneva wheel rotates, the Geneva wheel is stationary. Therefore, when the seed discharging plate rotates, no material shifting is performed, and the seeds are relatively stable while the material suction holes move to meet the positions of the seeds. Conversely, when the seed discharging plate (material suction holes) is stationary, the material shifting blades operate, thus avoiding interference caused by the movement of both during unstable adsorption and affecting the adsorption.

[0014] A further improvement of the technical solution of the present invention lies in that: a feedback cylinder is fixedly connected to the position of the partition plate where each chamber is located. The feedback cylinder corresponds to and communicates with each chamber one by one. A partition ring is fixedly connected to the middle position of the inner wall of the feedback cylinder. A first slide rod is slidably connected through the partition ring. One end of the first slide rod is fixedly connected to a piston plate, and the piston plate is in contact with the inner wall of the feedback cylinder. The end of the first slide rod away from the piston plate is fixedly connected to a limit plate. A first spring is sleeved on the outer part of the first slide rod between the limit plate and the partition ring.

[0015] With the above technical solution, by setting the feedback cylinder, when the material suction hole sucks the seeds, the corresponding chamber on the partition plate is blocked, resulting in an increase in negative pressure until it approaches the pressure in the distribution plate. During this process, due to the negative pressure effect, the piston plate moves towards the side close to the chamber, driving the first slide rod and the limiting part to move and compress the first spring to accumulate potential energy. When reaching the seed discharging area, since the communication hole is in communication with the external environment, the pressure in the chamber will be quickly released through the communication hole. At this time, due to the decrease in the pressure in the chamber, the first spring rebounds and pushes the limit plate, the first slide rod and the piston plate to reset, thereby enabling the chamber to obtain pressure compensation, that is, the negative pressure in the chamber will not be immediately released, so that the seeds will not be immediately released when rotating to the seed discharging area, but will stay for a while until the seed discharging plate is stationary and the pressure inside the feedback cylinder is completely released. At this time, the pressure in the chamber is not sufficient to adsorb the seeds, enabling the seeds to be released in a state without initial velocity and perform free-fall motion, thus reducing the problem that the seeds are easily damaged when released with an initial velocity.

[0016] A further improvement of the technical solution of the present invention is that the compensation mechanism includes a feeding rack, a pushing block is slidably connected between the inner walls of the feeding rack, a through slot for taking materials is provided in the middle of the pushing block, an input pipe is fixedly connected to the top of the feeding rack, the input pipe is funnel-shaped, and the top is communicated with the bottom of the seed discharging shell; an output pipe is arranged at the bottom of the feeding rack, and the output pipe is communicated with the discharge pipe; a second spring is fixedly connected between one end of the pushing block and one side of the inner wall of the feeding rack, a strip groove is provided on one side of the feeding rack, a push rod is fixedly connected to the side wall of the pushing block, and the push rod extends to the outside of the feeding rack through the strip groove; a linkage frame is hinged on one side of the inner wall of the protective shell, and a makeshift groove for the linkage frame to pass through is provided on the protective shell, one end of the linkage frame contacts with the push rod, and a top block used in cooperation with the linkage frame is fixedly connected to the side of the limit plate away from the first sliding rod; the edge of the through slot mouth is rounded.

[0017] With the above technical solution, when the suction hole leaks, the piston plate, the first slide rod and the limit plate in the corresponding feedback cylinder are all inactive, so that when the top block rotates to the discharge area, it will contact the linkage frame, and the seed plate moves to press the linkage frame, so that the linkage frame rotates, and at the same time, the other end of the linkage frame squeezes the push rod and drives the push block to move. Before the push block moves, the through groove on the push block faces the bottom end of the input tube, so that the seeds can fall from the seed discharge shell through the input tube into the through groove; when the push block is pushed, the through groove carries the seeds and moves to face the output tube, so that the seeds fall into the output tube, and then fall into the discharge tube along the output tube, that is, the compensation discharge is completed. In the above process, the second spring is compressed and accumulates potential energy.

[0018] A further improvement of the technical solution of the present invention is that: a mounting groove communicating with the inner wall of the feeding rack is opened on the top of the feeding rack, a wedge block is slidably connected between the inner walls of the mounting groove, a second slide rod is fixedly connected to one side of the wedge block, a fixed plate is fixedly connected to the inside of the mounting groove, the second slide rod penetrates the fixed plate and is fixedly connected to a pad, the second slide rod is slidably connected to the pad, the pad contacts the end of the pushing block, and a third spring is sleeved on the outside of the second slide rod and located between the wedge block and the fixed plate.

[0019] The above technical solution is adopted, by arranging a wedge block inside the feeding rack to temporarily block the seeds, so as to reduce the damage of the pushing block to the seeds; when the pushing block is not pushed, the third spring is in a compressed state; when the pushing block is pushed (for compensatory seed discharge), the pad loses the support of the pushing block, so under the rebound action of the third spring, the wedge is pushed to extend between the seeds to be discharged and the seeds at the bottom of the input tube, and drives the second slide bar and the pad to move, and the inclined surface of the wedge is extended to contact the seeds, and the arc surface at the bottom of the seed is cooperated with to lift the seeds upward and break away from the contact with the pushing block, thereby avoiding the problem of seed damage; and when the pushing block is reset, the pad is pushed to reset at the same time, and the wedge is driven to reset by the second slide bar, the third spring is compressed again, and the seeds can enter the through groove through the input tube.

[0020] A further improvement of the technical solution of the present invention is that a brush is fixedly connected to one side of the inner wall of the seed discharging shell, and the bristles of the brush are in contact with the seed discharging plate.

[0021] By adopting the above technical solution, a brush is arranged in the seeding housing, and the bristles thereof are in contact with the suction holes of the seeding plate, and the seeding plate moves relative to the brush during rotation, thereby brushing off the seed coat or debris, thereby reducing the problem of subsequent unstable adsorption caused by the debris; A further improvement of the technical solution of the present invention is that the pressing mechanism comprises a pressing roller, the outer side wall of the pressing roller is fixedly connected with a plurality of anti-sticking cloths, and the anti-sticking cloths are fixedly connected to the outside of the pressing roller in an annular shape and at equal intervals.

[0022] By adopting the above technical solution, in wet soil operation scenarios, the fabric structure can reduce the adhesion between soil and metal. The "folding structure" formed by the anti-stick cloth can shake off the soil during rotation, automatically peel off the residue on the surface of the roller, and maintain efficient operation of the equipment.

[0023] Due to the adoption of the above technical solution, the present invention has the following technical advances compared with the prior art: 1. The present invention provides a ridging seeder. By arranging a front furrow plow, shallow furrows can be plowed in advance before ridging. The positions of the shallow furrows are exactly the paths along which the conical parts at both ends of the ridging mechanism travel. The ridging mechanism can perform ridging based on the soil pile between two adjacent shallow furrows. During the ridging process, the conical part of the soil extends into the shallow furrow and applies force to the central part, thereby preventing the soil at the edge (the original shallow furrow position) from being over-compacted by the conical part. A rear ridge plow is arranged to "repair" the ridge body after furrowing and sowing, and push the soil scattered during the sowing process back to the top of the ridge, thereby preventing the ridge body structure from being damaged due to the soil backfilling into the ridge furrow after sowing and being compacted by the suppression mechanism, which is beneficial to the maintenance of the ridge body structure.

[0024] 2. The present invention provides a ridge-forming seeder, which divides a partition plate shared by various suction holes into a plurality of independent chambers, and each independent chamber is connected to a distribution plate in common. The distribution plate is evacuated, and negative pressure is transmitted through a connecting hole facing the air groove, so that the negative pressure can be transmitted to the chamber facing the air groove. In the above process, the distribution plate acts as a pressure-stabilizing tank, and an external air pump only needs to continuously maintain the pressure value of the distribution plate. Since the chambers of the distribution plate and the partition plate are connected through connecting holes, and an additional transfer chamber is provided, and the mutual disturbance between the suction holes is reduced due to the aperture limitation of the connecting hole, thereby reducing the influence of air pressure changes on the adsorption of seed particles.

[0025] 3. The present invention provides a ridging seeder. By setting a grooved wheel mechanism, the seed feeding mode of the seed discharging plate is changed from a continuous type to an intermittent type, so that there is enough time for the suction operation during the stop interval of the rotation of the seed discharging plate, thereby increasing the probability of the seeds being adsorbed and reducing the occurrence of missed seeding. Specifically, during the rotation of the ridging mechanism following the movement of the machine body, the driving wheel is driven to rotate through a transmission mechanism, and the first lever is driven to rotate around the central axis of the driving wheel, and the external grooved wheel is periodically toggled, so that for each rotation of the driving wheel, the corresponding external grooved wheel rotates by an arc, causing the driving shaft to rotate intermittently during the rotation of the ridging mechanism, thereby driving the seed discharging plate to feed intermittently and leaving enough time to adsorb the seeds.

[0026] 4. The present invention provides a ridging seeder. By setting a feedback cylinder, when the suction hole sucks the seeds, the corresponding chamber on the partition plate is blocked, causing the negative pressure to increase until it approaches the pressure in the distribution plate. During this process, due to the negative pressure effect, the piston plate moves towards the side close to the chamber, drives the first slide bar and the limiting part to move and compress the first spring to accumulate potential energy. When reaching the seed discharging area, the pressure in the chamber is quickly released through the communication hole. At this time, based on the decrease in the pressure in the chamber, the first spring rebounds and pushes the piston plate to reset, thereby enabling the chamber to obtain pressure compensation, that is, the negative pressure in the chamber is not immediately released, so that the seeds will not be immediately released when rotating to the seed discharging area, but will stay for a while until the seed discharging plate is in a static state and the pressure inside the feedback cylinder is completely released. At this time, the pressure in the chamber is not sufficient to adsorb the seeds, causing the seeds to be released in a state without an initial velocity and perform free-fall motion, thereby reducing the problem of easy damage when the seeds are released with an initial velocity.

[0027] 5. The present invention provides a ridging seeder. By setting a compensation mechanism, when the suction hole fails to suck, the piston plate, the first slide bar and the limiting plate in the corresponding feedback cylinder do not move, so that when the top block rotates to the discharging area, it will contact the linkage frame. Along with the movement of the seed discharging plate, the linkage frame is pressed, causing the linkage frame to rotate. At the same time, the other end of the linkage frame presses the push rod and drives the pushing block to move. Before the pushing block moves, the through groove on the pushing block is aligned with the bottom end of the input pipe, enabling the seeds to fall from the seed discharging housing into the through groove through the input pipe. When the pushing block is pushed, the through groove carries the seeds to move to be aligned with the output pipe, causing the seeds to fall into the output pipe and then fall into the discharging pipe along the output pipe to complete the compensation discharging.

Detailed implementation mode

[0031] The present invention will be further described in detail below in conjunction with embodiments.

[0032] Embodiment 1 As Figures 1 - 15 shown, the present invention provides a ridging seeder, including a machine body 1; further including: a front furrow plow 11, installed at the front of the machine body 1, for pre-loosening the soil and opening a shallow groove before ridging; a ridging mechanism 2, including a columnar part 21 and conical parts 22 at both ends of the columnar part 21, for squeezing the soil on both sides towards the middle to form a ridge body, and compacting the shallow grooves on both sides of the ridge body to form ridge grooves, and anti-slip teeth 23 are fixedly connected at equal intervals on the periphery of the conical part 22; a furrow opener, for opening a V-shaped seed furrow with a certain depth on the ridge surface at the top of the ridge body; a sowing mechanism 3, for quantitatively sowing seeds; a fertilizing mechanism, for applying fertilizers into the ridge grooves; a compensation mechanism, for sowing additional seeds when the sowing mechanism 3 misses sowing; a transmission mechanism, for using the power generated by the rotation of the ridging mechanism 2 to drive the sowing mechanism 3 and the fertilizing mechanism to work, including a sprocket and a chain for connecting the central shaft of the ridging mechanism 2 and the sowing mechanism 3 and the fertilizing mechanism; a rear ridge plow 12, for repairing the damaged ridge shape after furrowing, reshaping the ridge shoulders after furrowing and sowing, and gathering the overflowing soil through a curved profiling plate to restore the trapezoidal cross-section; a pressing mechanism, installed at the rear of the machine body 1, for compacting the seed furrow and the surface soil of the ridge body.

[0033] By setting the front furrow plow 11, it is possible to pre-plow shallow furrows before ridging, and the positions of the shallow furrows are exactly the paths along which the conical parts 22 at both ends in the ridging mechanism 2 travel. The ridging mechanism 2 can ridge based on the mounds of soil between two adjacent shallow furrows. During the ridging process, the conical parts 22 of the soil penetrate into the shallow furrows and apply force towards the central part, thus preventing the soil at the edge part (the original shallow furrow position) from being overly compacted by the conical parts 22. And a rear ridging plow 12 is set to "repair" the ridged body after ditch opening and sowing, pushing the soil scattered during sowing back to the ridge top, preventing the soil from backfilling into the furrow after sowing and being compacted by the compressing mechanism, which is beneficial to maintaining the structure of the ridged body.

[0034] Specifically, the front furrow plow 11 is located in front of the machine body 1. When the machine body 1 travels, the front furrow plow 11 first cuts into the soil. The plow tip is designed in a V shape, opening two symmetrical guide grooves, and at the same time loosening the surface compacted soil to disperse the subsequent ridging resistance. The columnar part 21 of the ridging mechanism 2 presses the soil in the middle, and the conical parts 22 at both ends squeeze the soil on both sides towards the midline to form a trapezoidal ridged body. Among them, the anti-slip teeth 23 on the periphery of the conical part 22 of the ridging mechanism 2 are embedded in the soil during rotation to prevent slipping and simultaneously compact the guide grooves to form standard furrows. The furrow opener opens a V-shaped seed furrow with a depth of 3 - 5 cm and a width of 5 - 8 cm in the center of the ridge top. At the same time, the fertilizing mechanism quantitatively applies fertilizers to the bottom of the furrow through a spiral fertilizer distributor. The seed metering device in the sowing mechanism 3 is set as a suction-type seed metering device, which can accurately suck the seeds and put them into the seed furrow. After the above-mentioned ditch opening and sowing, the soil on the ridge top spreads to both sides. By setting the rear ridging plow 12 in the shape of a curved profiling plate, the curved plow plate re-collects the soil turned out during ditch opening to the ridge shoulder, restoring the trapezoidal cross-section. Finally, the ridged body is compacted by the compressing mechanism to complete sowing.

[0035] Structurally, two seed metering channels of the sowing mechanism 3 and the compensation mechanism are adopted, which can compensate for sowing when the sowing mechanism 3 misses sowing. Through the above redundant design, the accuracy of sowing is guaranteed, and the operation effect is improved.

[0036] Embodiment 2 As Figure 3 、 Figure 4 and Figure 5As shown in the figure, on the basis of Embodiment 1, the present invention provides a technical solution: Preferably, the seeding mechanism 3 includes a seed box 31 and a seed discharging housing 32. A protective housing 33 is fixedly connected to the mouth of the seed discharging housing 32. One side of the inner wall of the protective housing 33 is rotatably connected to a driving shaft 310. One end of the driving shaft 310 is fixedly connected to a seed discharging plate 34. A driving structure 4 for controlling the rotation of the driving shaft 310 and the seed discharging plate 34 is arranged inside the protective housing 33; the seed discharging plate 34 is in contact with the mouth of the seed discharging housing 32. A plurality of suction holes 35 arranged in a ring shape are formed in the seed discharging plate 34. A ring-shaped partition plate 36 is fixedly connected to the side of the seed discharging plate 34 close to the protective housing 33. The inside of the partition plate 36 is equally spaced into chambers 311 equal in number to the number of suction holes. Communication holes 38 equal in number to the number of chambers 311 and communicating with each other are formed in the inner wall of the partition plate 36; a distribution plate 37 is rotatably connected to the inner wall of the partition plate 36. The distribution plate 37 is fan-shaped, and air grooves 39 are formed in the side wall. A sealing ring is arranged between the distribution plate 37 and the partition plate 36. An air pump is fixedly installed on the machine body 1. The air pump is communicated with the distribution plate 37 through a pipeline; an inlet pipe 314 communicating with the seed box 31 is arranged on one side of the seed discharging housing 32, and a discharge pipe 313 is arranged at the bottom. The bottom end of the discharge pipe 313 extends into the inside of the furrow opener. A partition plate 312 is fixedly connected to the inside of the seed discharging housing 32. The discharge pipe 313 and the inlet pipe 314 are respectively located on both sides of the partition plate 312; the aperture of the suction hole 35 is larger than that of the communication hole 38.

[0037] The existing pneumatic (air suction type) seed metering device usually adopts the method of directly connecting a negative pressure chamber to the suction hole 35 for suction. By rotating the seed discharging plate 34 and generating negative pressure at the position of the suction hole 35 at the same time, when the seeds move near the suction hole 35, they are adsorbed to achieve suction. However, the adsorption of seeds by the above-mentioned suction hole 35 is in a continuously changing dynamic process, which also makes the internal pressure of the negative pressure chamber shared by each suction hole 35 constantly change. As a result, some seeds with unstable adsorption postures, irregular self-structures, etc. may be adsorbed at the beginning, but will fall off after the above-mentioned adsorption pressure change, resulting in missed seeding. Such as referring to the appendix Figure 14Schematic diagram of the seed distribution structure shown. Among them, the seeding process is divided into four regions. Region I is the seed suction area, which is used to suck seeds when the suction hole 35 passes through the seed retention part; Region II is the seed delivery area, which is used to convey seeds; Region III is the seed discharging area, which is used to remove the negative pressure of the suction hole 35 to release seeds; Region IV is the seed cleaning area, which can remove the seeds or seed coat residues that have not been completely discharged in the seed discharging area. Since it is a probabilistic event that the suction hole 35 in Region I, the seed suction area, adsorbs seeds, although the probability of adsorbing seeds can be increased by means such as agitating the seeds, the adsorption time is still uncertain. And since each suction hole 35 shares a chamber 311, the internal pressure of each suction hole 35 keeps changing, which may cause the seeds that are not stably adsorbed in Region II, the seed delivery area, to fall off, resulting in missed seeding. By dividing the partition plate 36 shared by each suction hole 35 into several independent chambers 311, and each independent chamber 311 is jointly connected to the distribution plate 37. By evacuating the distribution plate 37 and then using the communication hole 38 facing the air groove 39 to transmit the negative pressure, the negative pressure can be transmitted to the chamber 311 facing the air groove 39. In the above process, the distribution plate 37 acts as a pressure stabilizing tank, and the external air pump only needs to continuously maintain the pressure value of the distribution plate 37. And since the distribution plate 37 and each chamber 311 of the partition plate 36 are also conducted through the communication hole 38, due to the addition of a transfer chamber 311 and being restricted by the aperture of the communication hole 38, the mutual disturbance effect between each suction hole 35 is reduced, thereby reducing the influence of air pressure change on the seed adsorption effect.

[0038] Specifically, the seeding plate 34 is driven to rotate by the driving structure 4, and the seeds adsorbed on the suction hole 35 are carried until they are discharged. When the suction hole is in Region I, the seed suction area, and Region II, the seed delivery area, the communication hole 38 is facing the air groove 39. The negative pressure in the distribution plate 37 can be transmitted to the corresponding chamber 311 of the partition plate 36 through the air groove 39 and the communication hole 38, and then the suction hole 35 continuously evacuates until seeds are adsorbed. The seeds pass through the seed delivery area and reach the seed discharging area. And the communication hole 38 in this area is facing the fan-shaped notch part of the distribution plate 37, that is, it is communicated with the external environment, so that the negative pressure in the chamber 311 of this area in the partition plate 36 will be released outward through the communication hole 38. After losing the negative pressure, the seeds are no longer adsorbed, so as to release the seeds. The seeds are discharged from the discharge pipe 313 after being released, and the discharge position is the ditching position of the ditching opener. Among them, a filter screen is arranged inside the suction hole 35 to prevent impurities or seed coats shed from the seeds from being sucked into the partition plate 36.

[0039] Among them, the aperture of the suction hole 35 is larger than the connecting hole 38, so that the pressure change in the chamber 311 of the separation plate 36 is always faster than that of the distribution plate 37, producing a certain hysteresis effect, thereby reducing the influence of the different pressures in the separation plate 36 (when the suction hole 35 sucks seeds and when it does not suck seeds) on the internal pressure of the distribution plate 37 (it takes time for the pressure to be transmitted through the connecting hole 38).

[0040] There are two parallel seeding shells 32 in the seeding mechanism, corresponding to the two seeding channels which act synchronously, that is, two seeds are discharged to the same position each time the seeding is performed.

[0041] like Figure 6 , Figure 7 and Figure 10 As shown, preferably, the driving structure 4 includes an outer groove wheel 43 fixedly connected to the outside of the driving shaft 310, the inner side of the protective shell 33 is rotatably connected to the driving wheel 41, the central axis of the driving wheel 41 is connected to the central axis of the ridging mechanism 2 via a sprocket and a chain transmission connection (i.e., a transmission mechanism), and a first lever 42 is fixedly connected to one side of the driving wheel 41, the first lever 42 is used in conjunction with the notch on the outside of the outer groove wheel 43, the central axis of the driving wheel 41 extends to the outside of the protective shell 33, and is connected to the ridging mechanism 2 via a transmission mechanism.

[0042] In the scheme, the rotation of the seeding plate 34 relies on the rotation of the ground wheel (the ridging mechanism 2 in the scheme) and is powered by the transmission mechanism. Therefore, the rotation of the seeding plate 34 is continuous and synchronized with the movement of the machine body 1. Although it can cooperate with the movement of the machine body 1 to perform synchronous seeding, the continuous rotation of the seeding plate 34 will also affect the probability of seed absorption. The seeds will be turned away from the position of the seeds in the suction hole 35 before the absorption is completed (when the seeds are at the position of the suction hole 35, the negative pressure in the chamber 311 corresponding to the suction hole 35 continues to increase, and the seeds will be absorbed after a period of time. However, if the seeding plate 34 continues to rotate, the negative pressure may increase to a level sufficient to absorb the seeds and the seeds will be turned away from the position, especially the seeds are piled in the seeding shell 32, so there is a certain absorption force requirement), so it is more likely to be missed. By setting a groove wheel mechanism, the seed delivery mode of the seed plate 34 is changed from a continuous mode to an intermittent mode (i.e., stop after rotating for a certain arc, and then stop after rotating again, and the action is cyclic but the overall rotation period remains unchanged), so that there is enough time for the suction operation in the stop gap of the rotation of the seed plate 34, thereby increasing the probability of seeds being adsorbed and reducing the occurrence of missed seeds; specifically, in the process of the ridging mechanism 2 rotating along with the movement of the machine body 1, the driving wheel 41 is driven to rotate through the transmission mechanism, and the first lever 42 is driven to rotate around the central axis of the driving wheel 41, and the outer groove wheel 43 is periodically driven, so that for every rotation of the driving wheel 41, the corresponding outer groove wheel 43 rotates for a certain arc, so that the drive shaft 310 rotates intermittently during the rotation of the ridging mechanism 2, thereby driving the seed plate 34 to rotate intermittently.

[0043] Example 3 like Figure 6 , Figure 7 and Figure 10 As shown, on the basis of Example 2, the present invention provides a technical solution: preferably, the distribution disk 37 is rotatably connected to the side away from the seed plate 34 with an inner groove wheel 57, the central axis of the inner groove wheel 57 is a hollow shaft, and the driving wheel 41 is fixedly connected to the side away from the first lever 42 with a second lever 53, and the second lever 53 is used in conjunction with the notch inside the inner groove wheel 57; the driving shaft 310 is a hollow rod, and the protective shell 33 is located inside the driving shaft 310 and is rotatably connected with a core rod 51, one end of the core rod 51 extends to the inside of the seed discharge shell 32 through the driving shaft 310 and is fixedly connected with a material-discharging blade 52; the inner side of the protective shell 33 is rotatably connected with a driven gear 56, and the outer wall of the inner groove wheel 57 is fixedly connected with a driving ring gear 55, and the driving ring gear 55 is meshed with the driven gear 56, and the central axis of the driven gear 56 and one end of the core rod 51 both extend to the outside of the protective shell 33, and are connected by a synchronous wheel and a synchronous belt transmission.

[0044] Since the seeding plate 34 rotates intermittently, the seeds stored in the seeding housing 32 are piled together and have poor fluidity, especially the seeds at the bottom, which are squeezed by the gravity of the seeds above and are not easy to move. The adsorbed seeds also need to overcome greater resistance before they can be carried. When the seeds at the bottom are arranged in a posture that is not easy to be adsorbed, the adsorption probability will be affected, resulting in missed sowing (there are gaps between the seeds themselves, and the gaps cannot be adsorbed, and only when the middle of any side of the seeds is facing the suction hole 35 can they be stably adsorbed); By setting the seed pushing blade 52, the stacked seeds can be pushed to reduce the weight of the seeds stacked in the middle, enabling the seeds located below during the movement of the machine body 1 to move, thereby increasing the probability that the seeds in the middle are directly opposite to the suction holes 35; specifically, during the rotation of the driving wheel 41, the second push rod 53 is also driven to make a circular motion around the center of the driving wheel 41, and periodically pushes the internal groove wheel 57, causing the internal groove wheel 57 to make an intermittent rotation. Through the transmission of the synchronous pulley and the synchronous belt, the core rod 51 is driven to rotate. Further, the seed pushing blade 52 is driven to rotate, so as to push the seeds in the middle to one side, reducing the accumulation of seeds in the middle, so that the seeds near the lower part in the middle can move along with the movement of the machine body 1; it should be particularly noted that the internal groove wheel 57 and the external groove wheel 43 share the same drive of the driving wheel 41 for operation, and their operating states are opposite, that is, when the internal groove wheel 57 rotates, the external groove wheel 43 is stationary, and when the external groove wheel 43 rotates, the internal groove wheel 57 is stationary. Therefore, when the seed discharging plate 34 rotates, no seed pushing is performed, and the seeds are relatively stable while the suction holes 35 move to meet the position of the seeds. On the contrary, when the seed discharging plate 34 (suction holes 35) is stationary, the seed pushing blade 52 operates, thus avoiding interference caused by the movement of the two during unstable adsorption, which affects adsorption.

[0045] Embodiment 4 As Figure 7 , Figure 9 and Figure 11 shown, on the basis of Embodiment 3, the present invention provides a technical solution: Preferably, a feedback cylinder 81 is fixedly connected to the position where the partition disk 36 is located in each chamber 311. The feedback cylinder 81 corresponds to and communicates with each chamber 311. A partition ring 82 is fixedly connected to the middle position of the inner wall of the feedback cylinder 81. A first sliding rod 83 is slidably connected through the partition ring 82. One end of the first sliding rod 83 is fixedly connected to a piston plate 84. The piston plate 84 is in contact with the inner wall of the feedback cylinder 81. The end of the first sliding rod 83 away from the piston plate 84 is fixedly connected to a limiting plate 85. A first spring 86 is sleeved on the outside of the first sliding rod 83 between the limiting plate 85 and the partition ring 82.

[0046] The existing seed metering device releases negative pressure when the seeds reach the seed metering area, thereby releasing the seeds. However, the seed discharging plate 34 continues to rotate, so that the seeds will inevitably carry a certain centrifugal force when released, resulting in the seeds being thrown out in a form with an outward movement tendency. Especially in this solution, the seed discharging disk makes an intermittent rotation and the total rotation period remains unchanged. Therefore, to make up for its stationary time, it has a faster speed when rotating, so that the seeds will be thrown out at a greater speed, resulting in the seeds being easily damaged by collision; By providing the feedback cylinder 81, when the suction hole 35 sucks the seeds, the corresponding chamber 311 on the partition plate 36 is blocked, so that the negative pressure increases until it approaches the pressure in the distribution plate 37. During the process, due to the negative pressure, the piston plate 84 moves toward the side close to the chamber 311, and drives the first slide bar 83 and the limit part to move and squeeze the first spring 86 to accumulate potential energy. When reaching the seeding area, since the connecting hole 38 is connected to the external environment, the pressure in the chamber 311 is quickly released through the connecting hole 38. At this time, based on the pressure reduction in the chamber 311, the first spring 86 is pressed. The spring 86 rebounds and pushes the limit plate 85, the first slide rod 83 and the piston plate 84 to reset, so that the chamber 311 obtains pressure compensation, that is, the negative pressure in the chamber 311 will not be released immediately, so that the seeds will not be released immediately when they rotate to the seeding area, but will stay temporarily for a period of time until the seeding plate 34 is in a stationary state and the internal pressure of the feedback cylinder 81 is completely released. At this time, the pressure in the chamber 311 is not enough to absorb the seeds, so that the seeds are released without initial velocity and move in free fall, thereby reducing the problem of seeds being easily damaged when released with initial velocity.

[0047] It should be particularly noted that when the suction hole 35 does not adsorb seeds, since the chamber 311 is directly connected to the outside (seed discharging housing 32) through the suction hole 35, the negative pressure is directly released from the suction hole 35, and the adsorption effect in the distribution plate 37 is transmitted to the chamber 311 at a slower speed, so that the pressure in the chamber 311 is at a low level, and this state is not sufficient to make the piston plate 84 move.

[0048] Example 5 like Figure 8 and Figure 12 As shown, on the basis of Example 4, the present invention provides a technical solution: preferably, the compensation mechanism includes a feeding frame 61, a pushing block 64 is slidably connected between the inner walls of the feeding frame 61, a through slot 65 for taking materials is provided in the middle of the pushing block 64, an input pipe 63 is fixedly connected to the top of the feeding frame 61, the input pipe 63 is funnel-shaped, and the top is connected to the bottom of the seeding shell 32; an output pipe 62 is provided at the bottom of the feeding frame 61, and the output pipe 62 is connected to the discharge pipe 313; one end of the pushing block 64 is connected to one side of the inner wall of the feeding frame 61 A second spring 66 is fixedly connected, a strip groove 610 is provided on one side of the feeding frame 61, a push rod 69 is fixedly connected to the side wall of the pushing block 64, and the push rod 69 extends to the outside of the feeding frame 61 through the strip groove 610; a linkage frame 67 is hinged on one side of the inner wall of the protective shell 33, and a clearance groove for the linkage frame 67 to pass through is provided on the protective shell 33, one end of the linkage frame 67 is in contact with the push rod 69, and a top block 68 used in conjunction with the linkage frame 67 is fixedly connected to the side of the limiting plate 85 away from the first sliding rod 83; the edge of the mouth of the through groove 65 is rounded.

[0049] Although the above solution can reduce the situation of missed suction in the suction hole 35, the problem of missed suction still belongs to a probability event, so there is still a possibility of missed seeding; When the suction hole 35 misses suction, the piston plate 84, the first sliding rod 83 and the limiting plate 85 in the corresponding feedback cylinder 81 are all inactive, so that when the top block 68 rotates to the discharging area, it will contact the linkage 67. Along with the movement of the seed plate 34 pressing the linkage 67, the linkage 67 rotates. At the same time, the other end of the linkage 67 squeezes the push rod 69 and drives the pushing block 64 to move. Before the pushing block 64 moves, the through groove 65 on the pushing block 64 is directly opposite to the bottom end of the input pipe 63, so that the seeds can fall from the seeding housing 32 through the input pipe 63 into the through groove 65; when the pushing block 64 is pushed, the through groove 65 carries the seeds to move to be directly opposite to the output pipe 62, so that the seeds fall into the output pipe 62 and fall along the output pipe 62 into the discharge pipe 313, that is, the compensated discharging is completed. In the above process, the second spring 66 is compressed and accumulates potential energy; After the linkage 67 swings a certain angle (the angle required to complete the above-mentioned compensated discharging), the top block 68 moves away and is at the end of the linkage 67. The movement of the top block 68 no longer pushes the linkage 67 to rotate, so that the linkage 67 no longer hinders the movement of the top block 68. At the same time, the top block 68 does not hinder the reset of the linkage 67. Furthermore, under the rebound of the second spring 66, the pushing block 64 is pushed to reset until the through groove 65 is directly below the input pipe 63, and at the same time, the push rod 69 is driven to move and the linkage 67 is pushed to rotate and reset to the initial position (when in the initial position, the linkage rod is limited by the relief groove on the protective housing 33).

[0050] As Figure 8 、 Figure 12 and Figure 15 shown, preferably, an installation groove 71 communicating with the inner wall of the feeding frame 61 is opened at the top of the feeding frame 61. A wedge block 74 is slidably connected between the inner walls of the installation groove 71. One side of the wedge block 74 is fixedly connected with a second sliding rod 73. A fixed plate 72 is fixedly connected inside the installation groove 71. The second sliding rod 73 penetrates through the fixed plate 72 and is fixedly connected with a backing plate 76. The second sliding rod 73 is slidably connected with the backing plate 76. The backing plate 76 contacts the end of the pushing block 64. A third spring 75 is sleeved on the outer part of the second sliding rod 73 and between the wedge block 74 and the fixed plate 72.

[0051] Considering that during the compensated seeding process, the pushing block 64 moves, and there are several seeds arranged vertically above the pushing block 64. Along with the movement of the pushing block 64, the seeds at the bottommost will be worn or even crushed; By arranging a wedge block 74 inside the feeding rack 61 to temporarily block the seeds, the damage of the pushing block 64 to the seeds is reduced; when the pushing block 64 is not pushed, the third spring 75 is in a compressed state; when the pushing block 64 is pushed (for compensatory seeding), the pad 76 loses the support of the pushing block 64, so under the rebound action of the third spring 75, the wedge block 74 is pushed to extend between the seeds to be discharged and the seeds at the bottom of the input pipe 63, and the second slide bar 73 and the pad 76 are driven to move, and the inclined surface of the wedge block 74 contacts the seeds after extending, and the arc surface at the bottom of the seed is cooperated with the seed to lift the seeds upward and break away from the contact with the pushing block 64, thereby avoiding the problem of seed damage; and when the pushing block 64 is reset, the pad 76 is pushed to reset at the same time, and the wedge block 74 is driven to reset by the second slide bar 73, the third spring 75 is compressed again, and the seeds can enter the through groove 65 through the input pipe 63.

[0052] like Figure 8 and Figure 14 As shown, preferably, a brush 10 is fixedly connected to one side of the inner wall of the seed discharging housing 32 , and the bristles of the brush 10 are in contact with the seed discharging plate 34 .

[0053] A filter structure is provided in the suction hole 35 to prevent the seed coat and debris from being sucked in, but the seed coat and debris are not easy to fall due to gravity in the seeding area. Therefore, a brush 10 is provided in the seeding shell 32. The bristles of the brush are in contact with the suction hole position of the seeding plate 34. During the rotation of the seeding plate 34, the brush 10 moves relative to the brush 10, thereby brushing off the seed coat or debris, reducing the problem of subsequent adsorption instability caused by the debris.

[0054] like Figure 1 and Figure 2 As shown, preferably, the pressing mechanism includes a pressing roller 91 , and a plurality of anti-sticking cloths 92 are fixedly connected to the outer side wall of the pressing roller 91 , and the anti-sticking cloths 92 are fixedly connected to the outside of the pressing roller 91 in a ring-shaped manner and at equal intervals.

[0055] In this embodiment, in the operation scenario of wet or sticky materials (such as wet soil, colloids), the cloth structure can reduce the adhesion between the soil and the metal. The "folding structure" formed by the above-mentioned anti-stick cloth 92 will throw away the soil during rotation, automatically peel off the residue on the surface of the roller, and maintain the efficient operation of the equipment.

[0056] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
